Ever since the rise of bodybuilding in the 20th century, scientists have been pushing the envelope with new ways to increase muscle mass in humans. Researchers always assumed that the only way for a human to get to inhuman levels of muscle was by using anabolic steroids. These drugs, while extremely effective, all work the same way: by introducing an outside hormone to the body. While steroids do indeed build muscle mass, they come with a whole host of side effects. What if you could achieve similar results without the side effects? Now you can, and you can do it with a SARM called YK-11.
What is YK-11
YK-11 is potentially the most powerful muscle building compound on the entire planet. I know that is a huge claim, but I will back it up. Out of all the SARMs I discuss on this site, I truly believe that YK11 is the most versatile and pound for pound strongest for building muscle mass. While other SARMs target specific androgen receptors in the body, YK11 actually inhibits myostatin. I’ll talk more about myostatin and follistatin next, but for now just know that the holy grail of building muscle is to inhibit myostatin. Before YK 11 hit the market, pharmaceutical companies have spent millions trying to figure out how to achieve this feat.
Myostatin and Why it’s Killing Your Gains
Myostatin is a myokine protein found in the body that serves one purpose: to prevent muscles from getting larger. Unless you have a rare condition, you have plenty of myostatin floating around in your body at this very moment. Even though you work out for hours and keep your diet clean, the simple fact is this: until you can lower the amount of myostatin in your body, you are not reaching your potential (ever). It sounds terrible, and it is.
This is why YK-11 is so exciting. It has the ability to drastically lower the amount of myostatin in your body. Just look at what happens when a cow is born with a myostatin deficiency:
Believe me when I say this. I have been in the fitness industry for over 10 years. Not once have I ever been so excited for a SARM (or any compound for that matter) to hit the market. YK-11 has the ability to completely transform your physique in ways previously unimaginable.
If you’re considering doing a cycle of YK11, you’re going to want to know how to dose it properly. For most users, 10mg per day is a good place to start. I also highly suggest splitting the doses and taking 5mg in the morning and 5mg at night. This SARM has a shorter half life, so you’re going to want to take it twice daily for the best results. The highest I’ve ever seen someone run this compound was at 25mg per day, and he had some insane gains. If you plan on doing a cycle, I’d suggest following a protocol similar to the one below:
Week one: 5mg in the morning and 5mg at night.
Week 2, 3, 4: Same as week one.
Weeks 5 – 8: Up dosage to 15mg per day. Do 5mg in the morning, 5mg pre work out, and 5mg at night.
Weeks 8-12 (optional): Up the dosage again to 20mg per day. Take 5mg in the morning, 10mg pre workout, and 5mg at night.
Is YK-11 better for bulking or cutting?
This is one of the reasons I love this SARM so much. It is extremely versatile and can be used for both. Typically I would advise to keep the dosage lower for cutting cycles, since your goal is going to be to maintain as much muscle mass as possible while you lose weight. If you are bulking, you can assess your tolerance and ramp all the way up to 20mg per day if you feel comfortable. A lot of users like to stack it with LGD 4033 for bulking as well.
What results to expect
By now you are probably just as excited as I am about this compound. Because of that, you want to know what kind of results to expect from your cycle of YK-11. This is going to depend on a lot of factors. The most obvious ones are what your training and diet look like. Another thing that can play a role is the dose you’re running. If you’re running the average dose of 10mg per day, it’s safe to say that you can expect the following:
For bulking cycles: Gains of 10 to 15lbs of muscle for 8 week cycles are not unheard of while running YK 11. Hardly any fat will be accumulated if your diet is good and protein intake is high.
For cutting cycles: Gains of 5 to 10lbs of muscle alongside 5 to 10lbs of fat loss are common. Keep your total calories down between 500 to 1000 of your TDEE during a cutting cycle.
Another reason that I love this SARM so much is that it does not possess any of the side effects that are normally found with steroids and other harsher SARMs. There is no risk for hair loss or gyno (gynocomastia aka man boobs). With that being said, listen to your body. If you feel that something is wrong then immediately stop taking it at once. I know one person who got diarrhea from taking YK-11 but that’s about the worst that can happen. Compared to steroids, this is very easy on the body.
Buy YK-11 Online
Unfortunately, you’re most likely not going to find YK11 at your local supplement store. Most SARMs, are only sold online as “research chemicals”. They are not approved for human consumption by the FDA. Because of that, you can only buy them from a manufacturer who labels them as such.
Something extremely important to look out for is the growing problem of fake yk-11 on the market today. You want to make sure that you buy yk11 from a reputable site that gets 3rd party lab testing done on their raw materials before selling to the public. This is why I recommend Proven Peptides. They’re one of the only companies that spends money to have their products tested before they make each batch. I’ve been using them for years and they have always delivered a quality product.
Commonly asked questions
If you’ve decided that this compound is going to make a great addition to your training routine, you most likely have some questions. Here are some commonly asked questions regarding YK11:
Do I need a PCT for YK11?
No, you do not. This SARM will not shut down your natural testosterone in any way. You do not need a post cycle therapy after running it.
Can I stack YK11 with LGD 4033 or Test?
Yes! Stacking YK with LGD 4033 is extremely popular among people who are bulking. You can also stack it with test e if you’re running it. One of the main benefits to this chem is that it stacks very well with other steroids and sarms.
Does it cause gyno?
NO! There is no conversion to estrogen with this or any other SARM for that matter. Gynocomastia is impossible.
How much does YK-11 Cost?
The cost of YK11 depends on who you get it from. Proven peptides is one of the most affordable suppliers out there. They charge $44.99 for a small bottle. You can also get bigger sizes for a discount.
Is YK 11 Safe?
Yes, it is very safe when used responsibly. Drink plenty of water and monitor your body to make sure there are no adverse reactions going on. As always, if you don’t feel right then immediately stop taking this and all other SARMs and go see your doctor.
YK-11 is a fantastic addition for anyone who wants to gain strength, size, and definition. It is extremely safe, versatile, and easy to dose. It stacks well with other compounds and it makes a great cycle base as well.
